Interactions
Cisapride is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementAmiodarone (HCl)Amitriptyline (HCl)Cisapride can cause ventricular arrhythmia due to prolong QT interval when given with Amitriptyline.MajorThis combination is contraindicated.AstemizoleCilostazoleCimetidine (HCl)Cimetidine increases the plasma concentration of cisapride by inhibiting its metabolic clearence.Increased level of cisapide results in prolongation of QT interval on ECG, ventricular arrythmia, cardiac arrest and sudden death.MajorCoadministration should be avoided. Famotidine, nizatidine, ranitidine considered as safer alternatives of cimetidine.ClarithromycinClarithromycin increases the plasma concentration of cisapride by inhibiting its metabolism result in prolongation of QT interval on ECG, ventricular arrythmia, cardiac arrest and death.MajorThis combination is considered contraindicated.Cyclosporin ACyclosporin increases the plasma concentration of cisapride by inhibiting its metabolic clearence.Increased level of cisapide results in prolongation of QT interval on ECG, ventricular arrythmia, cardiac arrest and sudden death.MajorCoadministration should be avoided.ErythromycinErythromycinFluconazoleFluconazole by inhibiting CYP450 3A4 increases plasma concentration of cisapride thus prolong QT interval leads to ventricular arrhythmias,cardiac arrest and sudden death may also occur.MajorCoadministration of both drugs sre contraindicated.Flurazepam (HCl)Halofantrine (HCl)Indinavir (Sulphate)Indinavir increases the plasma concentration of cisapride by inhibiting its metabolic clearence. Increased level of cisapide results in prolongation of QT interval on ECG, ventricular arrythmia, cardiac arrest and sudden death.MajorCoadministration should be avoided.ItraconazoleItraconazoleKetoconazoleKetoconazole increases the plasma concentration of cisapride by inhibiting its metabolic clearence resulting prolongation of QT interval, ventricular arrythmia, cardiac arrest and sudden death.MajorThis combination is considered contraindicated.Mibefradil (Di HCl)Miconazole (Nitrate)MoxifloxacinNelfinavirNevirapineOxycodoneQuinineQuinupristinThe manufacturer states that quinupristin may increase cisapride concentrations and cause QTc prolongation.Avoid concurrent use with cisapride.RitonavirRitonavir increases the plasma concentration of cisapride by inhibiting its metabolic clearence. Increased level of cisapide results in prolongation of QT interval on ECG, ventricular arrythmia, cardiac arrest and sudden death.MajorCoadministration should be avoided.TelithromycinThe use of Teicoplanin is contraindicated with cisapride.TerfenadineTicagrelorcisapride is CYP3A54 substrate, its exposure may increase by ticagrelor which is CYP3A4 enzyme inhibitorco administration is not recommendedVandetanibCisapride, vandetanib, arsenic and erythromycin all increase QT prolongation.Combination is not recommended.VORICONAZOLEVoriconazole may increase the serum concentration and toxicity of cisapride likely by decreasing its metabolism.Concomitant therapy is contraindicated. These interactions are sometimes beneficial and sometimes may pose threats to life. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required.
